LAMP.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed July 17,1905. Serial No. 270,166.

To all whom it may concern:

Be it known that I, GEORGEHAGKER, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

My invention relates to improvements in lamps; and it consists of the novel features hereinafter described and claimed.

The object of my invention is to construct a lamp to be used for heating incubators, and arranged to prevent the heating of the oil.

In the drawings, Figure 1 is a vertical longitudinal sectional view of my complete invention, showing the construction of the oilreceptacle and the egg-testing attachment applied to the chimney. Fig. 2 is a top plan View of the same. Fig. 3 is a detail perspective view of the egg-tester made use of in connection with my invention.

In the construction of the device as shown, I provide a base-section 4, comprising an oilreceptacle 5 and a wick-chamber 6. At the base of the wick-chamber is formed openings 7, through which oil is admitted from the oilreoeptacle to the wick-chamber. A flllingtube 8 is formed on the top of the oil-receptacle and is provided with a suitable plug 9. In the oil-receptacle is located a float 10, provided with a stem or indicator 11, projecting through the top of the oil-receptacle, and is for the purpose of indicating the height of the oil in the oil-receptacle. A deflector 12, consisting of a disk, is suitably connected to the wick-chamber and extends above and over the entire top portion of the oil-receptacle, forming a space 13 between said deflector and oil-receptacle, through which the air is admitted to continually circulate, thus preventing overheating of the oil within said receptacle.

To prevent overflow of the oil through the opening through which the indicator 1 1 operates,-a tube 14 is formed, which also acts as a support for the deflector 12. On each side opposite the tube 14 and filling-tube 8 I provide two braces 15,(shown by dotted lines in Fig. 2,) which also support the deflector 12.

Upon the wick-chamber 6 is mounted a suitable burner 16, and upon the burner the chimney 17, which consists, preferably, of a metallic structure and is provided with an opening 18, closed by a piece of transparent material 19, such as mica or the like, so that the operator may observe the flame of the lamp for the purpose of adjusting the same. On the chimney above the opening 18 is provided a hook 20 on which the operator may, when desired, attach the egg-tester 21, which consists of the tube 22, its end 23 shaped to flt the inclination of the chimney, and at the top is provided with a projection 24, in which is the perforation 25. By means of this projection and perforation the tester is attached to the hook 20, as shown in Fig. 1, and by the formation of this projection 24 recesses 26 are formed on each side and act as passages for the circulation of air to prevent the over heating of the tester. The opposite end of the tester is provided with a strip of flexible material 27, in which is an opening 28. This strip 27 is securely held to the tube 22 by a band 29. By means of this attachment the operator can at will test the eggs and will familiarize himself as to the condition and progress of the germ within the egg.

It has been found by practical experience that by providing the lamp with a separate wick chamber and perforations through which the oil is admitted from the oil-receptacle and the provision of ,a deflector above the receptacle the oil within the receptacle is kept at a much cooler degree than the oil within the wick-chamber, and by the application of the removable egg-testing device the fingers of the operator are never burned when coming in contact with the testing device while testing the eggs, and the eggs are prevented from being destroyed from excessive heat, as would be the case were the testing attachment formed integral with the chimney.

Having thus described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent, is

A lamp of the class described having a burner, a chimney mounted upon said burner, an opening formed in the chimney in alinement with the burner, a strip of transparent material located over the opening in the chimney, a hook formed on the chimney above the opening in combination with an eggtester comprising a tube supported by said hook, the end of said tube covered With a In testimony whereof I have signed my strip of flexible material having an opening name to this specification in presence of two against Which the egg is placed for testing, subscribing Witnesses. said tube having recesses formed in the end GEORGE HACKER. contacting With the chimney to permit the l Witnesses:
